/* ============================================================
   THE 808 — design tokens
   Palette drawn from the TR-808 drum machine: ink-blue chassis,
   orange-red step LEDs, warm paper for print-like contrast.

   Flat pass: every soft edge and glow removed in favor of hard,
   pixel-true geometry — the reduction logic of a Nike or Apple
   mark applied to 80s hardware. Same tokens, same components,
   sharper execution. No other file touched.
